2020-04-18	all: Fix implicit floating point to integer conversions.	stijn
	These are found when building with -Wfloat-conversion.
2020-04-18	all: Fix implicit conversion from double to float.	stijn
	These are found when building with -Wfloat-conversion.
2018-09-27	lib/libm/math: Add implementation of __signbitf, if needed by a port.	Damien George

2018-09-27	lib/libm/math: Fix int type in float union, uint64_t should be uint32_t.	Damien George
	A float is 32-bits wide.
2018-09-04	lib/libm/math: Make tanhf more efficient and handle large numbers.	Damien George
	Prior to this patch tanhf(large number) would return nan due to inf/inf.
2017-10-10	lib/libm: Remove implementation of log2f, use MP_NEED_LOG2 instead.	Damien George

2017-10-04	lib/libm: Fix tanhf so that it correctly handles +/- infinity args.	Damien George

2017-07-31	all: Use the name MicroPython consistently in comments	Alexander Steffen
	There were several different spellings of MicroPython present in comments, when there should be only one.
2017-06-14	lib/libm/math: Remove implementations of float conversion functions.	Damien George
	These implementations are incorrect (eg f2d and d2f don't handle special values like 0.0) and proper versions can be provided by libgcc (or equivalent depending on the toolchain). libgcc is now linked with the stmhal port so that library will provide these functions from now on.
2016-11-03	lib/libm: Move Thumb-specific sqrtf function to separate file.	Damien George
	This allows it to be used only when the hardware supports VFP instructions, preventing compile errors.
2015-12-18	lib/libm: Allow math funcs to be used by non-Thumb archs.	Damien George
	Requires addition of software implementation of sqrtf function.
2015-02-22	lib/libm: Add implementations of erf, erfc, lgamma, tgamma.	Damien George

2015-01-22	lib/libm: Add frexp and modf functions; use in stmhal; add tests.	Damien George
	Addresses issue #1081.
2014-12-30	stmhal: Add fake implementation of __aeabi_f2lz().	Paul Sokolovsky
	To make mp_obj_new_int_from_float() somehow work.
2014-12-18	lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal.	Damien George
	acoshf, asinhf, atanhf were added from musl. mathsincos.c was split up into its original, separate files (from newlibe-nano-2). tan was added. All of the important missing float functions are now implemented, and pyboard now passes tests/float/math_fun.py (finally!).
2014-09-13	py: Implement divmod, % and proper // for floating point.	Damien George
	Tested and working on unix and pyboard.
2014-09-11	py and libm: Add asinf,acosf; print higher precision for float.	Damien George
	Also use less stack space when printing single precision float. Addition of asinf and acosf addresses issue #851.
2014-08-29	lib, libm: Add back dummy definition of tanf.	Damien George

2014-08-29	lib: Add lib and libm, moving current files from stmhal.	Damien George
	Top-level lib directory is for standard C libraries that we want to provide our own versions of (for efficiency and stand-alone reasons). It currently has libm in it for math functions. Also add atanf and atan2f, which addresses issue #837.
